Initial analysis

The two-family residential building at 146-148 Valley Street in Noe Valley, owned by Sperow Investments LLC, is a two-story flats and duplex structure built in 1925. The property's recent improvements include a significant kitchen renovation completed in 2020, valued at $25,000, which encompassed the installation of new cabinets and lighting, along with associated plumbing and electrical work. Prior to this, in October 2017, there were street space permits issued, though the purpose isn't specified beyond the nominal cost.

The building's 311 call history from 2020 to 2024 reveals several recurring issues with parking violations in the vicinity, particularly involving vehicles parking on the sidewalk. Between November 2022 and August 2024, there were multiple reports of such violations, with varying outcomes ranging from resolved cases where officers were unable to locate the offending vehicle, to at least one citation issued in March 2021. Other notable incidents include a report of an abandoned pickup truck in February 2020 that was resolved by March 2, 2020, and a general cleaning request related to loose garbage in April 2020. The most recent 311 calls in August 2024 involved parking violations, though one case was deemed invalid due to incomplete reporting information. While these parking enforcement issues have been consistent over the years, they primarily affect the public right-of-way rather than the property itself.

Risk rating

How 146-148 Valley St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
